Bredal
spreaders utilise many features to ensure their accuracy reliability
and simplicity remains unrivaled
|
||
| Rather than using a gravity feed system Bredal machines use a floor belt to positively deliver material to the discs. The rate can then be regulated simply by altering the height of the door. | |||

Due
to this arrangement the machines always deliver a known volume regardless
of the condition of the material being spread from prilled nitrogen
to wet lime. The standard machine mounted calibration kit quickly
finds the bulk density (kg per litre) of the material and a single
setting chart is used to set the application rate for all matrials
|
|||
 |
 |
||
|
To
ensure the machines deliver the correct rate independant of forward
speed the floor belt is driven mechanicaly through a land wheel.
This wheel either runs against the tractor wheel in the case of
a mounted spreader or the machines rear tyre in the case of a trailed
machine.

All
Bredal machines utilise the double double overal principle of spreading.
All mounted machines are equiped as standard with Bredals 12 - 36m
discs and down shute pictured on the left. This set up features
6 (carbide coated) vanes per disc and uses an adjustable down shute
for exact positioning of fertilizer on the disc for maximum accuracy.
The trailed machines are delivered as standard with Bredals wide
spread lime/fertiliser set up which uses 4 vanes per disc pictured
on the right.

For
control of spread pattern at headlands the speed of the headland
side disc is reduced through a reduction drive simply by moving
a lever on the end of the spinner box.
|
|||
 |
 |
||
|
For
those requiring variable rate the spreaders can be equiped with
hydraulic belt drive connected to various types of electronic control.
All requirements regarding the calculation of area, quantity consumed,
application rate, weighing cells, time consumption, GPs control
etc can be facilitated using the LH 500 computer.

|
The weight of the trailed machines (up to 17 cubic meters of material) is carried by the strong chassis. On K65 through to K136 Hydraulic brakes are standard (air brakes available as an option)
|
The Floor belt runs along a powerfull carrying framewhich features stainless steel beds, plastic coated belt rollers with stainless steel shafts running on maintanance free bearings. The close sal between bearing and roller prevents dust and other foreign objects entering the bearings.
